SPECIFICATION forming part of Letters Patent No. 61 1,095, dated September `2O, 18968.

Application-filed November 13, 1897. Serial No. 658,473. (No model.) Patented in France December 21,1896,'N0.262,405;

To all whom it may concern:

Be it known that I, CONSTANT OASIMIR BAL- LIN, of the city of Paris, France, have invented an improved flexible hub applicable to the wheels of vehicles generally and more particularly to existing Wheels, (for which I have obtained Letters Patent in France for fifteen years, dated December 21, 1896, No. 262,405; in Belgium, foil fifteen years, dated January 11, 1897, No. 125,669,` and in"Eng land, for fourteen years, dated December 21, 1.896, No. 5,527,) of which the following is a full, clear, and exact description.

The invention forming the subject of the present application relates to an elastic or flexible hub of improved construction applicable to the wheels of vehicles of every description, and more particularly to existing wheels. Wheels of the latter class need not be changed or undergo any essential alteration in order to be refitted in accordance with this invention, it being only necessary to enlarge the diameter of the aperture or bore of the hub and to reduce its length to adapt it for the reception of the improved flexible device. The flexible arrangement enables the wheel to be strengthened at its weak or reduced part, its center being tightly compressed between two metal parts, which protect it from injury. Besides, a wheel fitted with the elastic device possesses great strength, while its elasticity is better distributed than over its circumference, all shocks or thrusts being relieved by an india-rubber cushion interposed between the wheel and the axle-journal, which consequently is not liable to be broken. This arrangement also obviates the inconveniences attending ythe application of india-rubber to the felly of the wheel, the rubber so applied being liable to rapid deterioration and apt to cause the wheels to slip upon wet roadways.

The invention will be clearly understood by reference to the accompanying drawings, which show, by way of example only, an arrangement carried out in accordance with my invention.

In the drawings, Figure 1 is an elevation of an existing carriage-wheel to which the improved iiexible-hub arrangement is applied.

Fig. 2 is a horizontal section thereof, taken on the line 1 2 of Fig. 1. Fig. 3 is a vertical section of the flexible hub separately drawn to an enlarged scale. Fig. 4 illustrates lthe manner of applying the lieXible-hub arrangement to the metal wheels of motor-cars. Fig. 5 is a horizontal section taken on the line 3 4 of Fig. 4, and Fig. 6 is a vertical section of the elastic hub separately and drawn to an enlarged scale.

In the several figures like parts are indicated by similar letters of reference'.

The method of applying the improved flexible arrangement to the wooden hub of an eX- isting wheel-say, to the wheel of awagon or carriage, as is assumed to be the casein the example given at Figs. 1 to 3-is as follows:

.The outside part-s of the wooden hub are first removed, so as to reduce its length, and the portion a thereof only is retained. The diameter of the opening or bore through which the axle-journal passes is then enlarged for the reception of the improved flexible device. After interposing the part b of the india-rubber sleeve between the bushing c of the hub and the portion' d of the casing these two halves of the device are inserted into the enlarged bore of the Wooden hub a, and a cap e is then screwed onto the part d of the casing. After inserting the part b of the india-rubber sleeve between the portions cA and d of the bushing and casing, respectively, these pieces are united by screwing to the corresponding parts b and c, and upon screwing the cap c' onto the part cl of the casing the wooden hub ct will be firmly compressed by the casing and the hoops f will be prevented from shifting. By these means a wheel of great flexibility and strength is obtained, while no change needrbe made inthe usual method of lubrication. l.

In applying the improved arrangement to the metal wheels of motor-carriages, as eX- empliiied at Figs. 4 to 6, the india-rubber sleeve b is interposed between the wheelbushing c and the outer case g, wherein the spokes h are set. The portion c' of the bushing is screwed into the correspondingpart c, after which the cap i is screwed into the interior of the case g.

. IOO

lVhere the improved fiexible hub is, employed, the wheel may be fitted with balls 7s, adapted to roll around the journal l of the axle.

It will be understood that the shapes and dimensions of the parts, the details of construction, and the materials employed in the manufacture of the improved device may vary without departing from the principle of the invention.

I claiml. In a vehicle-hub, the combination of a bushing formed by two sections having their inner` ends engaging each other and each provided with a flange at its outer end, a casing, an elastic cushion between the casing and bushing, and a screw-threaded cap engaging the casing, substantially as described.

2. In a vehicle-wheel, the combination of a flanged bushing formed of two sections having an interlocking engagement with each other, a casing formed of two sections having an interlocking engagement with each other7 acushion between the casing and bushing, and caps screwing on the casing, substantially as described.

3. In a vehicle-wheel hub, the combination of a two-part flanged bushing screwing one onto the other, a two-part casing screwing one upon I[he other, a two-part cushion between theV casing and bushing, and caps screwing on the casing, substantially as described.

4. The combination with a wooden hub, of atwo-part flanged bushing, a two-part casin g, one part of the Casin g projecting over the hub, a two-part cushion between the casing and bushing, a cap screwing onto the end of one section of the casing, and a second cap screw-- ing onto the other section of the casing and projecting over the end of the hub opposite that over which the section of the casing projects, substantially as herein shown and described.

5. The combination of the wheel having a sleeve forming an inner lining for the hub, a cap screwing on said sleeve, an interior, transversely-divided sleeve whose ends are engaged respectively by the irst-named sleeve and its cap, and an elastic cushion located between the two sleeves and between flanges on the interior sleeve, substantially as described.

The foregoing specification of my improved flexible hub applicable to the wheels of vehicles generally, and more particularly to existing Wheels, signed by lne this 23d day of October, 1897.

CONSTANT CASIMIR BALLIN.
